We Repair All Types of Furnace Issues in Boston

No matter what’s going wrong with your furnace, we understand how stressful it can be when you can’t count on your heating system to provide the warmth your home needs.

GEM is here to help Boston homeowners stay warm this winter; we take care of all types of furnace problems.

A furnace that won’t start can leave your home cold and uncomfortable fast. This issue could be the result of a faulty thermostat, an electrical problem, or a safety switch malfunction. The techs at GEM can quickly identify the cause and restore your heat so you can get back to comfort.

If some rooms feel warm while others stay chilly, your furnace may be struggling with airflow or ductwork problems. Uneven heating often points to dirty filters, blocked vents, or worn-out components. Our experts inspect your system to pinpoint the issue and restore balanced, consistent warmth throughout your home.

Banging, rattling, or squealing noises coming from your furnace are often signs of loose parts, worn belts, or internal damage. Ignoring these sounds can lead to bigger problems and costly repairs down the line. GEM’s team carefully diagnoses the source and provides safe, lasting repairs to keep your furnace running quietly.

When your furnace turns on and off frequently without fully heating your home, it’s short cycling; this is typically a sign of an underlying issue like a dirty filter, overheating, or incorrect sizing. This not only reduces comfort but also increases energy use and wear. GEM finds the root cause and restores your system to proper operation.

If your furnace is running but you’re not feeling much air from the vents, you could have a clogged filter, a failing blower motor, or a duct blockage. Reduced airflow makes your system work harder and lowers efficiency. Our technicians clean, repair, or replace the necessary components to get your heat flowing again.

A sudden spike in your heating costs is often a sign your furnace isn’t running efficiently. The underlying cause behind an inefficient furnace typically requires professional attention, and the experts at GEM are here to help. Our team can perform the repairs needed to restore efficiency and lower your monthly bills.

Nate came out first thing in the morning to help with my clogged sewer main. He was very professional and kind. He explained everything with no difficulty and offered multiple cost-tiered options. Mainly whether we would utilize a camera in the process of snaking the main. I appreciated being offered the option. We went with the camera process. So we could fully diagnose the issue, and determine if this would be a recurring problem.
We found roots growing in an old, 2-foot, cast-iron section of my main drainage pipe.
He used a blade attachment and cleared the obstruction to the best of his ability. Then left me with a quote to have the 2-foot section of cast iron replaced with PVC—which is only a small section that penetrated the foundation of my home.
I was very happy with the service, and most importantly the transparent approach which allowed me to make informed decisions.
Nate’s customer service skills were out of this world. I advise GEM Plumbing to invest in this young man.

Incredible company.
I had two whole house central AC units replaced (19 yrs old) and their team and other parts of the company (Plumbling, electrical, etc.) worked together to do an unbelieable installation in very hot conditions. My hats off to your company and we are so impressed that I contracted GEM to install a whole house 25kw generator.

I was able to schedule an appointment for the next day. The technician was great. Chris went over everything that needed to be done and explained it clearly. Very professional. He was also able to offer a discount and waived the fee for the service call. When I reviewed the bill that night, there was an error and the fee hadn’t been waived. When I called Gem the next day, they saw the error and immediately corrected it. Said the refund would be put on my credit card. Very happy with the service.

I am very happy with my well water pump service. David Chapman and his associate were professional, friendly and respectful. David showed me how to change my filter for which I am truly grateful.
It was super easy booking online The next day the dispatcher, (unfortunately I don’t know her name) called to offer an earlier appointment. She was very polite and kind.
My whole transaction was smooth and pleasant from start to finish!
